Abstract:
A spectra analysis of eight Seyfert galaxies shows that while seven have soft excesses in their spectra, with no low-energy absorption, ESO 140-G43 exhibits low energy absorption, and may have weak soft excess that is hidden by its 10 exp 21/sq cm absorber. It is suggested that soft excesses are a common feature of Seyfert galaxies, and soft excess detection depends on low-energy absorption in the line-of-sight to the source. This and other results obtained suggest that the fluorescence from warm material can produce a high fluorescence yield for the Fe line
